Mega-commit to bring in both, the STK500v2 support from Erik 

Walthinsen, as well as JTAG ICE mkII support (by me).

Erik's submission has been cleaned up a little bit, mostly to add his
name and the current year to the copyright of the new file, remove
trailing white space before importing the files, and fix the minor
syntax errors in his avrdude.conf.in additions (missing semicolons).

The JTAG ICE mkII support should be considered alpha to beta quality
at this point.  Few things are still to be done, like defering the
hfuse (OCDEN) tweaks until they are really required.  Also, for
reasons not yet known, the target MCU doesn't start to run after
signing off from the ICE, it needs a power-cycle first (at least on my
STK500).

Note that for the JTAG ICE, I did change a few things in the internal
API.  Notably I made the serial receive timeout configurable by the
backends via an exported variable (done in both the Posix and the
Win32 implementation), and I made the serial_recv() function return a
-1 instead of bailing out with exit(1) upon encountering a receive
timeout (currently only done in the Posix implementation).  Both
measures together allow me to receive a datastreem from the ICE at 115
kbps on a somewhat lossy PCI multi-UART card that occasionally drops a
character.  The JTAG ICE mkII protocol has enough of safety layers to
allow recovering from these events, but the previous code wasn't
prepared for any kind of recovery.  The Win32 change for this still
has to be done, and the traditional drivers need to be converted to
exit(1) upon encountering a timeout (as they're now getting a -1
returned they didn't see before in that case).

The JTAG ICE also uses a serial communication protocol which is similar
to the STK500 firmware version 2 one. However, as the JTAG ICE is
intented to allow on-chip debugging as well as memory programming, the
protocol is more sophisticated.
(This protocol can also be run on top of USB, but AVRDUDE by now only
supports the RS-232-based option.)
Only the memory programming functionality of the JTAG ICE is supported
by AVRDUDE.

Specify the bit clock period for the JTAG interface (JTAG ICE only).
The value is a floating-point number in microseconds.
The default value of the JTAG ICE results in about 1 microsecond bit
clock period, suitable for target MCUs running at 4 MHz clock and
above.
Unlike certain parameters in the STK500, the JTAG ICE resets all its
